FNDECL is the declaration node of the function. This is given to the
|
1995-02-21 23:59:56 +01:00
|
|
|
|
macro RETURN_POPS_ARGS to determine whether this function pops its own args.
|

|

1996-12-11 14:58:10 +01:00
|
|
|

FUNTYPE is the data type of the function. This is given to the macro
|
|
|
|
|
RETURN_POPS_ARGS to determine whether this function pops its own args.
|
|
|
|
|
We used to allow an identifier for library functions, but that doesn't
|
|
|
|
|
work when the return type is an aggregate type and the calling convention
|
|
|
|
|
says that the pointer to this aggregate is to be popped by the callee.
|
1992-01-17 23:48:42 +01:00
|
|

|

|
|
STACK_SIZE is the number of bytes of arguments on the stack,
|
2000-03-03 00:50:11 +01:00
|
|
|
|
ROUNDED_STACK_SIZE is that number rounded up to
|
|
|
|
|
PREFERRED_STACK_BOUNDARY; zero if the size is variable. This is
|
|
|
|
|
both to put into the call insn and to generate explicit popping
|
|
|
|
|
code if necessary.
|
1992-01-17 23:48:42 +01:00
|
|
|
|
|
|
|
|
|
STRUCT_VALUE_SIZE is the number of bytes wanted in a structure value.
|
|
|
|
|
It is zero if this call doesn't want a structure value.
|
|
|
|
|
|
|
|
|
|
NEXT_ARG_REG is the rtx that results from executing
|
|
|
|
|
FUNCTION_ARG (args_so_far, VOIDmode, void_type_node, 1)
|
|
|
|
|
just after all the args have had their registers assigned.
|
|
|
|
|
This could be whatever you like, but normally it is the first
|
|
|
|
|
arg-register beyond those used for args in this call,
|
|
|
|
|
or 0 if all the arg-registers are used in this call.
|
|
|
|
|
It is passed on to `gen_call' so you can put this info in the call insn.
|
|
|
|
|
|
|
|
|
|
VALREG is a hard register in which a value is returned,
|
|
|
|
|
or 0 if the call does not return a value.
|
|
|
|
|
|
|
|
|
|
OLD_INHIBIT_DEFER_POP is the value that `inhibit_defer_pop' had before
|
|
|
|
|
the args to this call were processed.
|
|
|
|
|
We restore `inhibit_defer_pop' to that value.
|
|
|
|
|
|
1994-06-02 13:24:33 +02:00
|

CALL_FUSAGE is either empty or an EXPR_LIST of USE expressions that

Another reason to preallocate is if we have a machine (like the m88k)

where stack alignment is required to be maintained between every

pair of insns, not just when the call is made. However, we assume here

that such machines either do not have push insns (and hence preallocation

nonzero, and targetm.calls.strict_argument_naming() returns zero,

this machine will be able to place unnamed args that were passed

in registers into the stack. So treat all args as named. This

independent of the function declaration.

We cannot do so in the following cases:

|
|
- if the type has variable size
|

|

|
|
|
|

|
Which padding can't be supported depends on the byte endianness.
|
|
|
|
|
|
|
|
|
|
A value in a register is implicitly padded at the most significant end.
|
|
|
|
|
On a big-endian machine, that is the lower end in memory.
|
|
|
|
|
So a value padded in memory at the upper end can't go in a register.
|
|
|
|
|
For a little-endian machine, the reverse is true. */
